Floor-mount electromagnetic door holder

The Edwards Signaling floor-mount holder secures a single door in the open position using a 120 VAC or 24 VAC/DC coil that draws 0.015 A at 24 V. A powder-epoxy aluminium finish protects the lock body, which measures 4-13/16 inches long and projects 6-7/16 inches from the floor. UL listing and FM approval confirm compliance with fire and life-safety standards.

Suited for fire-door hold-open applications

Installers who need a floor-mounted release device for a single swinging door will find the 25 to 50 lb adjustable holding force matches typical corridor requirements. The unit is not intended for surface-wall or overhead mounting, nor for double-door configurations that require a separate armature plate on each leaf. Buyers needing a different voltage coil or a wall-mount housing should select another model.

Adjustable 25 to 50 lb holding force

The magnetic circuit can be set anywhere between 25 and 50 pounds of pull, allowing the installer to match the force to the door weight and closer spring strength. This single adjustment determines whether the holder will keep the door open reliably without exceeding the force allowed by the fire-code rating.

Questions about this item

Should I choose the 12 V or 24 V version for my installation?

The unit draws .015 A at 24 V AC/DC and is also rated for 12 V operation; select the voltage that matches your existing access-control power supply.

What does the 25 to 50 lb holding force mean when the holder is mounted on a fire-rated door?

It provides enough magnetic force to keep the door open during normal use yet releases automatically when the fire-alarm signal cuts power to the coil.

How do the UL Listed and FM Approved ratings affect the wiring and voltage I must use?

The listings certify the holder for 120 V AC input and 24 V AC/DC control circuits; wiring must follow the listed voltage ratings to maintain compliance.
